Mathias Ellmann is a research assistant at the Applied Software Technology Group (MAST), Complex Systems Engineering (CSE) at the University of Hamburg. He is a Ph.D. in computer science and studies teaching and learning methods for higher education at the University of Hamburg. He received a Master of Science degree in industrial engineering and management with majors in international information systems (IIS) and information and communication systems (I&C) and minors in economics as industrial management, marketing, or macroeconomics at the University of Erlangen-Nuremberg. He received a Bachelor of Engineering degree in electrical engineering and information technology with majors in energy and automation technology from the Technical University of Applied Sciences in Regensburg. He received an apprenticeship diploma in energy technology and led/took part in several projects at the German Heart Centre Munich, BMW FIZ or in the Max Planck Institute in Munich.
In his Ph.D. he applied several empirical methods (descriptive statistics, topic clustering etc.) and algorithms (sequence algorithms, topic modeling and machine learning algorithms etc.) to understand similar software development documentation. He especially focused on their characteristics as well as on their lexical relations between them. He used machine learning algorithms to classify the software development documentation based on their types of similarity and identified them from a quantity of potential documentation candidates.
In his master he applied several empirical methods (descriptive and summary statistics etc.) to understand navigation signals from several GNNS receivers in different surroundings (city, suburbs, or airport) to evaluate their best application area. He also studied interferences in frequency bands in different surroundings (city, village, or industrial areas) that were used for services as alarm systems, phones or others to evaluate potential overloads. In his bachelor he studied potential risks and failures of a communication module for a transportation system.
Besides his recent studies he has been working in several software engineering and research departments. The departments were located in different domains as testing, automation and control, and web services. He used several programming languages (Python, MATLAB, VBA and C++, C#, Java as well as HTML and Java Script), version control systems (Git, SVN..) and requirement systems to perform the development tasks.
